Description

FIELD OF THE INVENTIONThe present invention relates to an elastic tensioner for accelerating a bolt or arrow for a hand launcher. The present invention furthermore relates to a hand-held firing device for firing bolts or arrows with such an elastic clamping device.BACKGROUND ARTArm breasts and their modifications, such as gun arm breasts, are used to shoot arrows over longer distances. The structure and the mode of operation of armbras is sufficiently known and historically shown, so that no basic explanations of the prior art are required.A gun arm breast is highly resembled in appearance to a gun, but it lacks the shaft characteristic of most arm breasts which is ajar to the shoulder during aiming and shooting. Instead, gun arm breasts are held on the handle in the hand. Nevertheless, the action of gun arm brushes is comparable to that of arm brushes. In particular, arm breasts and gun arm breasts are characterized by an arch with a chord tensioned therein. The bow usually contains two levers which project laterally from the shaft or handle. A disadvantage here is that these protruding levers are relatively bulky, in particular when a wide throw width is to be achieved.SUMMARY OF THE INVENTIONAgainst this background, the object of the present invention is to provide a compact clamping device and a compact hand firing device, wherein an arrow or bolt can be fired with a suitable firing width.According to the invention, this object is achieved by an elastic clamping device having the features of claim 1 and / or a hand launcher having the features of claim 7.Accordingly, the following is provided:an elastic clamping device for accelerating a bolt or arrow for a hand launcher: having a first end configured for fixation to a hand launcher; having a second end displaceable relative to the first end configured for receiving and accelerating a bolt or arrow; and having an elastic clamping element connecting the two ends, wherein the elastic clamping element extends substantially in a firing direction of a bolt or arrow to be accelerated.a hand firing device for firing bolts or arrows: having a gun-shaped housing; and having an elastic clamping device according to the invention, wherein the elastic clamping device is connected to the gun-shaped housing.The idea on which the present invention is based is to replace the bow of an armbrus or pistol armbrus with the more compact elastic clamping device in order to fire an arrow or bolt with a comparable throw width as in the armbrus. The elastic clamping device is integrated in the hand launcher or arrow gun. In this case, the elastic clamping element extends in a clampable manner substantially in the firing direction of the bolt or arrow to be accelerated.In the sense of the present invention, the elastic clamping element extends substantially in a firing direction if a longitudinal axis of the elastic clamping element deviates from the firing direction by at most 10°. The longitudinal axis corresponds in particular to the axis of the elastic clamping element in which the elastic expansion is provided. Consequently, the elastic tension member substantially stretches in the weft direction.An advantage of the hand launcher according to the invention comprising the elastic tensioning device according to the invention is that the hand launcher can be hosted. Thus, the hand firing device according to the invention can be carried, for example, in a holster, i.e. a pocket for guns, revolvers, Kellnergeldbörsen or other objects for the purpose of rapid access.Advantageous embodiments and refinements emerge from the further dependent claims and from the description with reference to the figures of the drawing.According to one embodiment, the elastic clamping device further comprises a lockable linear guide element which is fastened to the second end and is configured to hold the elastic clamping device in a ready-to-fire, tensioned state. In the tensioned state, in particular the elastic tensioning element is tensioned substantially in the weft direction. In this way, the elastic clamping device can be immediately prepared for firing the arrow. As soon as the locking of the linear guide element is released, the arrow or bolt can be accelerated. Advantageously, for releasing the locking of the lockable linear guide element, a significantly lower force is required than for tensioning the elastic tensioning device. In the tensioned state, the elastic tensioning element can be stretched or compressed, for example. In addition, the elastic tensioning element can be tensioned in a relaxed state substantially in the weft direction.According to a further embodiment of the elastic clamping device, the linear guide element is designed as a sliding guide or as a roller guide. Thus, the clamping of the elastic clamping device or of the elastic clamping element can be fixed along a predetermined axis. Furthermore, friction and consequently a required clamping force during clamping can be reduced.According to a further embodiment, the elastic clamping element has at least one elastic rubber band for providing a potential energy when the elastic clamping device is brought into the ready-to-fire, clamped state. For example, the elastic tension member may include two, three, four, or more elastic rubber bands arranged in a layered manner. Thus, elastic rubber bands having different properties, particularly different elastic properties, can be combined with each other. For example, the two, three, four or more elastic rubber bands may have different elasticity and / or length from each other, so that the potential energy can be increased stepwise. For example, the at least one rubber band is of comparable design to a rubber band used in centrifuging or twinning.According to a further development, the elastic clamping device further comprises a deflection element for deflecting the at least one rubber band by 160° to 200°, preferably by approximately 180°. Optionally, the elastic clamping device can comprise a plurality of deflecting elements, wherein the plurality of deflecting elements deflect the at least one rubber band in each case or together in total by 160° to 200°, particularly preferably by approximately 180°. Approximately 180° in the sense of the present application denotes an angle in the range from 175° to 185°. a plurality of deflection elements (6), in particular deflection rollers, for deflecting the at least one rubber belt (5), wherein the plurality of deflection elements (6) each deflect the at least one rubber belt (5) by 160° to 200°, preferably by approximately 180°. That is, when the plurality of deflecting elements deflect the at least one rubber band by 160° to 200°, respectively, the at least one rubber band forms a serpentine course between the first end and the second end. This can also be referred to as multiple deflection of the rubber bands. The at least one rubber band can thus be arranged very compactly.The deflecting element is designed, for example, as a deflecting roller. In this way, friction during the tensioning and the relaxing of the at least one rubber band can be reduced. Preferably, the at least one rubber band is attached to the lockable linear guide element continuously from the first end via the deflection roller.According to one embodiment of the hand firing device, the housing has a carriage for tensioning the elastic tensioning device, wherein the carriage is mechanically coupled to the second end of the elastic tensioning device, such that the elastic tensioning device can be brought by the carriage from a relaxed state into a ready-to-fire, tensioned state. In particular, the elastic clamping element can be brought by the carriage from the relaxed state into the ready-to-fire, tensioned state. The elastic clamping device or the elastic clamping element can thus be clamped in a simple and intuitive manner. In the interior of the slide, for example, a stop can be provided, against which the second end abuts in the relaxed state. When the elastic clamping device is tensioned, the slide can be displaced relative to the housing, wherein the stop moves the second end along in the same direction.The carriage can furthermore contain, for example, a grip element. The grip member may be provided at a rear end of the carriage to pull on the carriage. For example, the grip element is designed such that it can be gripped with two or three fingers.By pulling on the slide or clamping handle, the lockable linear guide element is pulled rearward and the elastic clamping device or the elastic clamping element is clamped, for example brought into the ready-to-fire, clamped state. In this case, the lockable linear guide element can be locked, for example, by a trigger of the hand firing device or the trigger can be coupled to a locking means. By actuating the trigger, the linear guide element together with the arrow can accelerate by relaxing the elastic clamping device or the elastic clamping element, for example by the plurality of rubber bands.According to a further embodiment of the hand firing device, the elastic clamping device comprises a reversibly lockable clamping device for clamping the first end of the elastic clamping device. In this way, the elastic clamping device can be replaced if necessary. Alternatively, the first end of the elastic clamping device can be adjusted. This means, for example, that the at least one rubber band can be made tighter or looser in the relaxed state by opening the reversibly lockable clamping device and closing it with a changed length of the rubber band.According to a development of the hand launcher, the reversibly lockable clamping device is arranged on an underside of the hand launcher such that it is accessible to a user. This means that the elastic clamping device, for example the at least one rubber band, can be clamped on the underside of the hand launcher. Thus, the user can operate the clamping device quickly and easily, i.e. without tools, for example.According to a further development of the hand firing device, the reversibly lockable clamping device is secured by means of a hook-shaped latching element.According to a further embodiment of the hand launcher, the elastic tensioning device is at least partially enclosed by the housing. The elastic clamping device can thus be better protected against damage or weathering, in particular UV radiation. Preferably, the elastic clamping device is completely surrounded by the housing. Advantageously, the elastic clamping element, for example the at least one rubber band, can be guided not on the outside, that is to say outside the housing, but on the inside, that is to say inside the housing.The above embodiments and developments can be combined with one another as desired, if appropriate. In particular, all features of the coupling system or of the coupling device can be transferred to the associated method for configuring the coupling system, and vice versa.Further possible embodiments, developments and implementations of the invention also include combinations of features of the invention described above or below with respect to the exemplary embodiments, which combinations are not explicitly mentioned. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.CONTENT INDICATION OF THE DRAWINGThe present invention is explained in more detail below with reference to the exemplary embodiments indicated in the schematic figures of the drawings.

They illustrate embodiments and, in conjunction with the description, serve to explain principles and concepts of the invention. Other embodiments and many of the advantages mentioned are evident with reference to the drawings. The elements of the drawings are not necessarily shown to scale with respect to each other.In the figures of the drawing, elements, features and components that are the same, functionally the same and act the same-unless stated otherwise-are each provided with the same reference numerals.DESCRIPTION OF EMBODIMENTSFIG. 1 shows a schematic illustration of an elastic clamping device 1 according to an exemplary embodiment.The elastic clamping device 1 comprises a first end 2 designed for fixing to a hand launcher and a second end 3 displaceable relative to the first end 2. the second end 3 is designed for receiving and accelerating a bolt or arrow A. The first end 2 is here the left end of the elastic clamping device 1 and the second end 3 is here the right end of the elastic clamping device 1.Furthermore, the elastic clamping device 1 comprises an elastic clamping element 5 connecting the two ends 2, 3. The elastic clamping element 5 extends substantially in a firing direction X of a bolt or arrow A to be accelerated. Consequently, the firing direction X is oriented to the left here. Consequently, the arrow A is also shown in the weft direction X.In FIG. 1, the elastic clamping element 5 is illustrated only symbolically as a spiral in order to clarify its elastic property. Even if the elastic tensioning element 5 may be assumed to be a spiral spring, it is not limited to such a configuration. Alternatively to the spiral spring, the elastic tensioning element 5 can be designed, for example, as a rubber band or the like.In addition, the elastic clamping device 1 comprises a lockable linear guide element 4, which is fastened to the second end 3. The lockable linear guide element 4 is displaceable along the firing direction X. Furthermore, the lockable linear guide element 4 is designed to hold the elastic tensioning device 1 in a ready-to-fire, tensioned state. For this purpose, the lockable linear guide element 4 can be locked, for example, by means of a corresponding locking means (not shown).FIG. 2 shows a schematic side view of an elastic clamping device 1 according to a further exemplary embodiment, wherein the elastic clamping device 1 is installed in a hand launcher 10 according to an exemplary embodiment. The hand launcher 10 is used, for example, to launch bolts or arrows A.The hand launcher 10 comprises a gun-shaped housing 11 and an elastic clamp 1 which may be formed, for example, as shown in Figure 1. The elastic clamping device 1 is connected to the gun-shaped housing 11. The gun-shaped housing 11 is characterized by a handle for carrying or holding the hand launcher 10 with a single hand.The elastic clamping device 1 is suitable for accelerating a bolt or arrow A for the hand launcher 10. The elastic clamping device 1 here comprises, by way of example, a first end 2 designed for fixing to a hand launcher and a second end 3 displaceable relative to the first end 2. the second end 3 is designed for receiving and accelerating a bolt or arrow A.Furthermore, the elastic clamping device 1 comprises an elastic clamping element 5 connecting the two ends 2, 3. The elastic clamping element 5 extends substantially in a firing direction X of a bolt or arrow A to be accelerated.In addition, the elastic clamping device 1 comprises a lockable linear guide element 4, which is fastened to the second end 3. The lockable linear guide element 4 is displaceable along the firing direction X. For example, the linear guide element 4 is designed as a sliding guide. The linear guide member 4 can slide within the housing 11.Furthermore, the elastic clamping element 5 comprises a plurality of elastic rubber bands 5 for providing a potential energy when the elastic clamping device 1 is brought into the ready-to-fire, tensioned state. By way of example, four, five or six similar rubber bands are provided here, which are arranged in layers. The plurality of rubber bands 5 may be arranged as bundles, for example.The four, five or six similar rubber bands 5 are, for example, deflected by 180° by a deflection roller 6. Due to the deflection of the rubber bands by 180°, the elastic tensioning element 5 continues to extend substantially along the weft direction X. The short extension transversely to the weft direction X in the region of the deflection roller plays a negligible role in relation to the extension in the weft direction X. Thus, the elastic clamping element 5 has a longitudinal axis which is substantially parallel to the firing direction X.In addition, the elastic clamping device 1 can comprise a reversibly lockable clamping device 13 for clamping the first end 2 of the elastic clamping device 1, as is illustrated in FIG. 2. Here, the reversibly lockable clamping device 13 is secured by means of a hook-shaped latching element 15.The gun-shaped housing 11 partially encloses the elastic clamping device 1.FIG. 3 shows an isometric perspective view of the hand launcher 10 of FIG. 2 More specifically, the housing 11 is indicated merely in phantom so that the components disposed in the housing 11 are more visible.As can be seen easily in FIG. 3, the housing 11 contains a limiting means 16 for limiting a displacement of the lockable linear guide element 4, wherein the limiting means 16 is oriented transversely to the firing direction X.The hand launcher 10 further comprises a storage chamber for arrows A. In the storage chamber, the arrows A can be stacked one above the other. A lowermost arrow A of the stacked arrows A can be fired from this position through a suitable opening of the housing 11.The hand launcher 10 further comprises a trigger 7 for activating the launcher. Upon actuation of the trigger 7, the elastic tensioning device 1 changes very rapidly from a tensioned state to a relaxed state.FIG. 4 shows a schematic view of an underside 14 of the hand launcher 10 from FIG. 2 It is clearly shown that the reversibly lockable clamping device 13 is arranged on the underside 14 of the hand launcher 10 such that it is accessible to a user.FIGS. 5 and 6 show a schematic side view of a hand launcher 10 according to a further embodiment with an elastic tensioner 1 according to a further embodiment. In this case, FIG. 5 illustrates the elastic clamping device 1 in a relaxed state and FIG. 6 in a ready-to-fire, tensioned state.The hand launcher 10 and the elastic tensioner 1 of the further embodiment illustrated in FIGS. 5 and 6 substantially correspond to the hand launcher 10 and the elastic tensioner 1 according to FIG. 2, respectively. The slide 12 is mechanically coupled to the second end 3 of the elastic clamping device 1, so that the elastic clamping device 1 can be brought by the slide 12 from the relaxed state into the ready-to-fire, tensioned state.In addition, the carriage 12 here contains, by way of example, a grip element. The grip member is provided at a rear end of the carriage 12 (the rear end corresponds to the right end in FIGS. 5 and 6 ) to be able to pull the carriage 12. For example, the grip element is designed as a T-grip.The hand launcher 10 here further comprises a lever device 17. That is, by operating the trigger 7, the lever device 17 can be moved. In the ready-to-fire, tensioned state, the lever device 17 locks the lockable linear guide element 4, as illustrated in FIG. 6. When the lockable linear guide element 4 has been brought into the ready-to-fire, tensioned state and locked by means of the slide 12, the slide 12 can be released by the user. Preferably, the carriage 12 then returns to its home position as shown in Fig. 5.FIG. 7 shows an isometric perspective view of a hand launcher 10 according to another embodiment. The hand launcher 10 is optically similar to a conventional gun. Like conventional guns, the hand launcher 10 may also be holisticated. Advantageously, the hand launcher 10 can have approximately the same external dimensions as a conventional gun to fit in existing holsters.In this case, the housing 11 of the hand launcher 10 completely encloses the elastic tensioning device 1, for example.Although the present invention has been fully described above with reference to preferred exemplary embodiments, it is not restricted thereto, but can be modified in a variety of ways.List of reference characters1 Elastic clamping device 2 First end 3 Second end 4 Lockable linear guide element 5 Elastic clamping element 6 Deflecting element 7 Trigger 10 Hand firing device 11 Housing 12 Slide 13 Clamping device 14 Underside 15 Latching element 16 Limiting means 17 Lever device A Arrow X Firing direction
